Samba Configuration on RHEL 8.2: SMB1 disabled -- no workgroup available

I've been taking a crack at configuring Samba to allow my Guest OS (RHEL 8.2), running on Oracle VM VirtualBox 6.1.8, to talk to my Host OS (Win10) following this guide here. Unfortunately, using a Shared Folder via Guest Additions does not provide the dev environment that is required.

So upon running:
# smbclient -U {myuser} -L localhost
I get the following:

Enter WORKGROUP\{myuser}'s password: Sharename Type Comment --------- ---- ------- athena Disk ATHENA Server # my desired share, mapped to root IPC$ IPC IPC Service (Samba 4.11.2) {myuser} Disk Home Directories
SMB1 disabled -- no workgroup available

I believe that this error: SMB1 disabled -- no workgroup available is blocking my Host OS' ability to detect the share on the network via the VM Box's IP

So far my google-fu has turned up no pertinent results, so any insights would be appreciated

It isn't an error, it is a fact. You have 'protocol = SMB3' , which is actually 'server max protocol = SMB3', which is the default, so you don't need it. There is also a default setting of 'server min protocol = SMB2_02', which means that SMBv1 is turned off and you need SMBv1 for network browsing. Because this is Linux, you have two options, browse to the share via UNC or set up Avahi on both machines
